CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 515,185, dated February20, 1894.

Application iiled April 20, 1893. Serial No. 471,108. (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, SAMUEL G. WILBER, a citizen of the United States,residing at Lake Hill,in the county of Ulster and State of New York,have invented a new and useful Car- Coupling, of which the following isa specification.

The invention relates to improvements in car couplings.

The object of the present invention is to improve the constructionl ofcar-couplings and to providea simple and inexpensive one which willcouple automatically, and which may be readily uncoupled without goingbetween cars.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings: Figure l is a perspective view of a car-couplingconstructed in accordance with this invention. Fig. 2 is a longitudinalsectional view. Fig. 3 is a transverse sectional view. Fig. 4 is a planview of the car coupling. Fig. 5 is a detail view of the spring actuatedblock.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 designates a draw-head, having a longitudinal link-opening in which ismounted a spring-actuated block 2, provided with a longitudinal opening3 and adapted to be engaged by a link 4, when cars come together forcoupling to cause a spring-actuated couping-pin-carrying arm 5 to betripped.

The spring-actuated coupling-pin-carrying arm has a coupling-pin 6connected with its front end and its rear end is mounted on a transversepin 7, which is arranged in ears 8, extending upward from the top of thedrawhead, near the back thereof. The rear end of the spring-actuated arm5 is provided with a shoulder 9, which is engaged by one arm 10 0f aspiral spring ll; the arm .l0 is formed by extending one end of thespiral spring, and an arm 12, for engaging the draw-head, is formed byextending the other end of the spiral spring. The spring-actuated arm 5is provided with a depending heel 13, arranged below the transverse pin7, and adapted to be engaged by the upper end of a trip-lever 14,

which is fulcrumcd on a transverse pin 15, and which has its lower endarranged in the opening of the spring-actuated block. The upper end ofthe lever is arranged in advance of the heel of the spring-actuated armand is recessed to be engaged by the front edge of the heel and isadapted to maintain the springactuated arm in an elevated position tohold the coupling-pin in position preparatory to coupling. When the linkenters the drawhead for coupling it engages the spring-actuated blockand moves the upper end of the trip-lever out of engagement with theheel of the spring-actuated arm, thereby permitting the spring to causethe arm 5 to descend. As soon as the spring-actuated arm is raised, theblock engages the lower end of the lever and moves the same forward,thereby carrying the upper end of the lever rearward in engagement withthe heel of the spring-actuated arm to maintain the latter in elevatedposition. The follower block has its front face or end concavelyrecessed, and it is actuated by a spiral spring 16, arranged in rear ofit and engaging its rear end.

It will be seen that the car-coupling is simple and inexpensive inconstruction, automatic in operation, and does not necessitate personsgoing between cars.

The front end ofthe spring-actuated arm is provided with an eye, and anysuitable means may be provided for enabling the coupling-pin to beelevated from the sides and top of a car.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention. y

The curved recess at the front end of the follower block is adapted toengage the adjacent end of the link 4 with sufficient pressure to holdthe link in any desired position for coupling to enable the link toreadily enter the draw-head of an approaching car.

What I claim is- 1. In a car coupling, the combination of a draw-head, acoupling pin, an arm hinged at its rear end to the draw-head andarranged on top thereof and provided with a depending heel and havingits front end connected to the coupling pin, a spring-actuated blockmounted in the draw-head and provided with IOO a longitudinal opening,and a trip-lever fulcrumed on the draw-head and having its upper endengaging the heel of said arm and having its lower end loosely arrangedin the opening of the spring-actuated block, substantially as described.

2. In a car-coupling, the combination of a draw-head, a coupling-pin,ears rising from the draw-head, a transverse pin arranged in the ears,an arm having its rear end mounted on the pin and provided with adepending heel and having its front end connected to the coupling-pin, aspiral spring mounted on the transverse pin and engaging the arm, a

having its lower end arranged in the opening of the block and its upperend provided with a recess to engage the yheel of said arm,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.
